I'll tell you couple of things:
1. You will never mine that 1.34 BTC in a year since the difficulty will increase. That's just a current prediction. Companies that sell mining contracts never tell you that.
2. You will mine some bitcoins for eg. 0.65 in a year and their price can be much more than the predicted value or can be less, so you don't know are you going to be profitable or not. If the price keeps rising - probably yes.
3. At current rate you could buy roughly 0.5 BTC today and just keep it for a year and sell it... But maybe with mining you could dig more in the end buy you need to have the patience to wait for 2 years to see.
Also, here's a good piece of advice: NEVER reinvest mined bitcoins into buying hashpower.
Keep digging boys and girsl:

PS: According to your post you're making ~$20/day ($7k year) not $600/day as in your sig
